The method is in the main as follows, allowing, however,.a sufficiently wide margin for modificationsin the application of the materials 'mentioned:--First-, make a mixture consisting of about thirty parts cocoa-nut oil twice melted, and ten parts salt waterin which five parts onions have been cooked out. Then add to this mixture fifteen parts of a liquid decoction consisting of birch bark cooked out in vinegar, five parts extract of oakbark, five parts turpentine, fifteen parts diluted potash lye and fifteen parts soda lye. This mass is carefully mixed and then well cooked together. After this let it stand for about fourteen days. After this time it is melted, and

rials must be left to the discretion of the operator in any given case. If it is desirable, the mixture is lastly filtered (strained), and may then be evaporated to a solid mass. When it is to be used dissolve the requisite portion of this mass in a sutficient quantity of water, preferably in rain water. Then apply-this solution to the fabric by meansof a brush or by ru bbing it into the fabric whereby the fabric so treated will become clear, clean and fresh looking like new goods.
